My house rules on resting, long rests are different

No more full heals of HP on long rests, how silly. Now, hit dice need to be conserved! Unless you take a week off or something, which to me seems realistic after days of fighting.
Short Rest
A Short Rest is a period of downtime, at least 1 hour long, during which a character does nothing more strenuous than eating, drinking, reading, and tending to wounds.
A character can spend one or more Hit Dice at the end of a Short Rest, up to the character’s maximum number of Hit Dice, which is equal to the character’s level. For each Hit Die spent in this way, the player rolls the die and adds the character’s Constitution modifier to it. The character regains Hit Points equal to the total. The player can decide to spend an additional Hit Die after each roll. A character regains one Hit Die upon finishing a Long Rest, as explained below.
Edit
Long Rest
A Long Rest is a period of extended downtime, at least 8 hours long, during which a character sleeps or performs light activity: reading, talking, eating, or standing watch for no more than 2 hours. If the rest is interrupted by walking, fighting, casting Spells, or similar Adventuring activity—the characters must begin the rest again to gain any benefit from it.
At the end of a Long Rest,
a character regains one hit point per character level plus its constitution modifier. The character additionally loses one level of exhaustion if they have any. The character also regains
one Hit Die, and a character can spend any hit dice it has as if it had a short rest.
A character can’t benefit from more than one Long Rest in a 24-hour period, and a character must have at least 1 hit point at the start of the rest to gain its benefits.
